When species become endangered,it is an indicator that the health of vital ecosystems is beginning to unravel or decline.

Endangered species are often an indicator that their ecosystems are in trouble, as species depend on their habitats to provide food, shelter, and other resources. When an ecosystem starts to unravel or decline, it can lead to the decline of species living there, eventually leading some to become endangered or even extinct. Therefore, the health of ecosystems is crucial in maintaining biodiversity and protecting endangered species.
